[Solved] Make GameObjects spawn at custom locations (Slender like)

Question

(Sry, maybe my English isn't perfect) Can I make multiple gameObjects spawn at custom locations, with custom rotation? Or is it easyer to put all of them to their location, but only activate 8 random picked ones when the scene starts?

I want to do that like in Slender (there are 10 possible locations but only 8 pages). Thanks!

Ok, I found a really good script for it (AlucardJ´s Slender Guide)

You can set the spawnpoints (as much as you want) and set multiple pages (gameObjects, not prefabs) to spawn.

 #pragma strict
 import System.Collections.Generic; // to use List
  
 public var spawnPoints : Transform[];
 public var paperPrefabs : Transform[];
  
 private var availableSpawnPointsList : List.< Transform >;
 private var spawnList : List.< Transform >;
  
  
 function Start()
 {
     ChooseRandomSpawnPoints();
     SpawnPapers();
 }
  
  
 function ChooseRandomSpawnPoints()
 {
     var i : int = 0;
    
     availableSpawnPointsList = new List.< Transform >();
     spawnList = new List.< Transform >();
    
     // add all spawn points to a list
     for ( i = 0; i < spawnPoints.Length; i ++ )
     {
         availableSpawnPointsList.Add( spawnPoints[i] );
     }
    
     // choose a different random position for each paper prefab
     for ( i = 0; i < paperPrefabs.Length; i ++ )
     {
         var rndPos : int = Random.Range( 0, availableSpawnPointsList.Count );
        
         spawnList.Add( availableSpawnPointsList[rndPos] ); // add this to the spawn point list
        
         availableSpawnPointsList.RemoveAt( rndPos ); // remove this from the available points list
     }
    
 }
  
  
 function SpawnPapers()
 {
     // spawn paper at each location
     for ( var i : int = 0; i < paperPrefabs.Length; i ++ )
     {
         var paper : Transform = Instantiate( paperPrefabs[i], spawnList[i].position, spawnList[i].rotation );paper.name = "Paper";
         paper.name = "Paper";
     }
 }

It works fine, but I´ll try @MagicoCreator´s script, too.

you can define an array of Vector3s (or GameObjects) and shuffle the array, and instanctiate at the first X elements with Random rotation: for example: GameObject[] Positions;

 function Start(){
   //Shuffle the array
     for (int t = 0; t < Positions.Length; t++ )
     {
         GameObject tmp = Positions[t];
         int r = Random.Range(t, Positions.Length);
         Positions[t] = Positions[r];
         Positions[r] = tmp;
     }
   //instantiate your objects
   for(int i = 0; i < howmanyyouwanttoinstantiate; i++){
     Instantiate(YourObject,Positions[i].transform.position,Random.rotation);
   }
 }

if you want to randomize the rotation only on Given axes you can use

 Quaternion.Euler(Random.Range(0,360),Random.Range(0,360),Random.Range(0,360));

instead of Random.rotation, you can replace the Random.range with the number you want on the axis

Thanks! I found another good script at AlucardJ´s Slender Guide, but I´ll test which one is better.
